Background and Objectives High-intensity focused ultrasound (HIFU) can produce small zones of thermal damage. A HIFU procedure is non-invasive and it can achieve rejuvenation of facial skin. Fractional CO₂ laser resurfacing delivers thermal damage to the pixilated columnar zone of the skin and so evoke collagen remodeling, the same as HIFU. In many cases, the patients who want rejuvenation with HIFU are also good candidates for cutaneous photorejuvenation such as can be accomplished via fractional CO₂ resurfacing. If patients are treated in a single session by remodeling both the superficial and deep compartments of skin by using both modalities, then improvement in rhytides and tightening of sagging skin will optimize the aesthetic result. Materials and Methods Between May 2014 and January 2018, a total of 44 patients were treated with combination HIFU and fractional CO₂ laser resurfacing according to our protocol. First, the HIFU was applied to the entire face with an average of 300 treatment lines. Immediately after HIFU treatment, the ultrasound gel was washed off and then fractional CO₂ laser resurfacing was performed. We evaluated the patients using 4-point grading scales. The clinician examined the skin for evidence of complications after the completion of treatment. Results All the patients' skin quality showed improvement. Further. the clinical results after duel modality treatment were substantially better than that after the use of either modality alone. The recovery times and the incidence of adverse events when quickly and consecutively performing both treatments were similar as compared to those with employing stepwise treatment. We encountered no complications whatsoever. Conclusion When compared with stepwise therapy, combination therapy with HIFU and fractional CO₂ resurfacing offers better, safer and more effective clinical results. Thus, for targeting multiple layers of aging facial skin, this combination therapy can be safely performed in a single treatment session.

목적: 만성 발목관절 외측 불안정성 환자에 대한 변형 Brostrom 술식에서 단일 봉합나사와 이중 봉합나사를 이용한 기법간의 임상 결과를 후향적으로 비교하고자 하였다. 대상 및 방법: 본원에서 봉합나사를 이용한 변형 Brostrom 술식을 시행받은 환자들 중 최소 1년 이상 추시가 가능하였던 37례를 대상으로 하였다. 모든 수술은 동일한 술자에 의해 이루어졌으며 단일 봉합나사를 이용한 경우가 17예, 이중 봉합나사를 이용한 경우가 20예 였다. 임상적 결과의 평가는 Karlsson 점수 및 Sefton의 평가법을 이용하였고, 발목관절의 기계적인 안정성에 대한 방사선학적 평가로 Telos 기기를 이용한 전방 전위 및 내반 스트레스 검사가 이용되었다. 결과: Karlsson 점수는 단일 봉합나사군이 술 전 평균 45.2점에서 술 후 89.4점으로, 이중 봉합나사군이 술 전 평균 46.4점에서 90.5점으로 각각 호전되었다. Sefton 평가법상 단일 봉합나사군은 우수가 7예, 양호가 8예, 보통이 2예 였고, 이중 봉합나사군은 우수 8예, 양호 10예, 보통 2예로 나타나 각각 15례(88.2%), 18례(90%)에서 만족스러운 결과를 보였다. 스트레스 방사선검사 상 거골 경사각과 거골 전방전위는 단일 봉합나사군이 술 전 평균 13.6도, 8.6 mm에서 술 후 최종 추시시 5.4도, 4.1 mm로, 이중 봉합나사군이 술 전 평균 14.1도, 8.4 mm에서 술 후 3.9도, 4 mm로 각각 호전되었으며 두 기법간에 술 후 거골 경사각의 유의한 차이를 보였다(p<0.05). 결론: 만성 발목관절 외측 불안정성에 대한 변형 Brostrom 술식에서 단일 봉합나사와 이중 봉합나사를 이용한 기법간에 술 후 임상 결과의 유의한 차이는 없었으나, 발목관절의 기계적인 안정성은 이중 봉합나사군에서 더 우수하였다. 단일 봉합나사와 이중 봉합나사를 이용한 변형 Brostrom 술식 모두 효과적인 치료 방법이라고 생각되며, 향후 운동 선수들을 대상으로 한 치료결과 및 생역학적 분석이 필요할 것으로 생각한다.

목 적 : Henoch-$Sch{\ddot{o}}nlein$ 신염은 소아 말기 신부전증의 중요한 원인 질환이며 발병시 심한 단백뇨를 보이거나 신증후군의 소견을 나타낼 때 및 고혈압, 질소혈증 등을 동반한 급성 신장염의 소견을 보일 때는 예후가 나쁘며 또한 신생검 소견상 병변이 심할수록 경과가 나쁘다고 보고되고 있다. 그러나 이들은 예후 결정 인자로서 충분치 못하며 HS 신염 환아들은 장기 추적 관찰이 반드시 필요하다는 의견이 부각되고 있다. 이에 저자들은 지난 10여년간 HS신염으로 입원하여 신생검을 받은 환아 59예를 대상으로 발병시의 임상 양상 및 신생검 소견에 따른 환아들의 임상 경과 및 예후를 알아보고자 후향적 조사 방법으로 본 연구를 시행하였다. 대상 및 방법 : 대상 환아는 1987년부터 1999년까지 경북대학교병원 소아과에서 HS신염으로 진단되어 신생검을 받은 환아 59예를 대상으로 하였으며 신생검의 기준은 1개월 이상 지속되는 심한 단백뇨 (1일 1 g/m2 이상의 뇨단백배설), 신증후군 (심한 단백뇨 및 혈청알부민 2.5 g/dl 이하) 및 1년 이상 지속되는 혈뇨 또는 단백뇨를 동반한 혈뇨로 하였다. 환아는 임상양상에 따라 단독 혈뇨군, 단백뇨를 동반한 혈뇨군 및 심한 단백뇨군으로 분류하였으며 신생검 소견은 International Study of Kidney Disease in Children (ISKDC)의 분류에 따라 grade I-V로 분류하였다. 59예중 49예가 1-2년간 추적 관찰되었으며 30예는 3-4년 이상 추적 관찰되었다. 추적 관찰 기간 중 정규적인 뇨검사, BUN, creatinine 등의 혈청검사 및 Ccr또는 DTPA scan을 이용한 GFR을 측정하여 신기능의 변화를 관찰하였다. 결 과 : 대상 환아의 연령 분포는 6-10세가 32예 (54.2$\%$)로 가장 많았으며 남아 33예 여아 26예로 남아가 다소 많았다. ISKDC 분류에 따른 조직 소견은 Grade I 이 2예, Grade II 44예, Grade III이 13예였으며 Grade IV, V는 한 예도 없었다. 고혈압, BUN 및 creatinine의 증가 및 Ccr이 감소된 경우는 없었으며 발병 초기에 심한 단백뇨를 보인 경우는 모두 25예였으며 이들은 Grade II 44예 중 19예 (43$\%$), Grade III 13예 중 6예 (46$\%$)로서 Grade II, III간에 유의한 차이가 없었다. 환아들의 임상 경과는 1-2년 추적 관찰된 49예중 정상뇨 소견 15예 (30.6$\%$), 현미경적 혈뇨 20예 (40.8$\%$) 중등도 이하의 단백뇨를 동반한 혈뇨 11예 (22.5$\%$) 였으며 심한 단백뇨가 지속된 경우는 3예 (6.1$\%$)였다. 3-4년 이상 추적 관찰된 30예에서는 각각 18예 (60.0$\%$), 2예 (6.7$\%$), 8예 (26.6$\%$) 및 2예 (6.7$\%$) 였다. ISKDC 분류의 Grad에 따른 임상 경과는 Grade II에서 뇨검사 소견의 호전율이 낮았으며, 지속적인 단백뇨 소견을 보인 경우가 많았다 (p<0.05). 초기 임상 양상에 따른 임상 경과는 추적 관찰 기간 중 뇨검사 소견의 정상화와는 관련성이 없었으나 심한 단백뇨군에서는 3-4년 이상 추적 관찰된 10예 중 2예에서 지속적인 심한 단백뇨를 보였다. 결 론 : ISKDC 분류에서 Grade I, II, III의 HS신염 환아의 예후는 대다수에서 3-4년 이내에 호전되는 양상을 보였고 발병시 심한 단백뇨를 보인 환아에서만 추적관찰기간중 지속적인 심한 단백뇨를 보여주어 발병시 심한 단백뇨가 환아의 임상 경과와 유관할 것으로 생각된다.

Objectives : The aim of this study is to observe clinical characteristics and treatment outcomes of inpatients admitted to a Korean medicine hospital for shoulder pain based on magnetic resonance imaging(MRI) findings. Methods : 28 patients with MRI data were included. Data on MRI findings, duration of pain, and treatment effects were collected. To measure treatment outcomes, verbal numerical rating scale(VNRS), range of motion(ROM), and a clinical condition grading system were used. Results : 1. The patient population was 75.0 % female and 39.3 %(n=11) belonged to the 51~60-year-old age group. In the under 40 population, 1 or less MRI findings were found. 2. As for the type of disorder, 82.1 % of the patients were diagnosed with 'Supraspinatus lesion', 39.3 % with 'subacromial-subdeltoid(SA-SA) bursitis', and 28.6 % with 'Adhesive capsulitis' 3. Numerous correlations could be made between duration of pain and MRI findings. 'rotator cuff full thickness tear' was more prevalent in acute shoulder pain patients, and 'Adhesive capsulitis' in chronic patients. 4. VNRS and ROM at the time of discharge had significantly improved as compared to VNRS and ROM at the time of admission. 5. As for correlation between MRI findings and clinical condition grade, patients diagnosed with 'rotator cuff partial tear' reported to be in 'good' condition or better whereas those with 'rotator cuff full thickness tear' reported to be in 'fair' condition or worse. Conclusions : Patients admitted to a Korean Medicine hospital for shoulder pain had varying degrees of severity as shown on MRI. Almost all lesions responded well to Korean medicine treatment.

Objects : The purpose of this study is to investigate the effect of Su-Gi therapy for Bell's palsy by using Y-system(Yanagihara's unweighted grading system). Methods : We investigated 25 patients with Bell's palsy who had visited in the M, H Korean medicine hospital in Gyeonggi Province from December 27th, 2010 to April 8th, 2015. The Su-Gi therapy was done by 1 times daily. And each patients had been treated more than 25 days. We evaluated the change of them by using Y-system. Results : 1. We investigated 25 patients with Bell's palsy. 80% of the patients were females(20 patients), 20% of the patients were male(5 patients). The average age of patients was 47±15.15. The average period of Adm. treatment was 64% of the patients(16 patients) have left facial palsy, 36% of the patients(9 patients) have right facial palsy. 2. The mean Y-system score before treatment was 17.80±6.2, and the mean score after 25th days treatment was 33.68±4.0. Changes in the mean Y-system Score for each case according to the treatment days was increased significantly. 3. The mean Y-system score after 4th days treatment had increased by an 1.24±2.7 as compared to before treatment, the score after 10th days treatment was 8.7±4.7, the score after 14th days treatment was 11.84±5.8, the score after 20th days treatment is 14.72±6.7, and the score after 25th days treatment was 15.88±6.9. Every score was significantly increased. Conclusions: 1. Su-Gi therapy can be defined that is mainly using the hands to touch or movement of the human body skin, meridians and acupuncture points, muscles, joints and so on. And that is the treatment to communicate and harmonize to the meridians and acupuncture points, and to prevent of diseases, and to keep health. 2. All names of An-Gyo, An-Ma, Jum-Hyul, Chu-Na, massage, and so on should be referred to as Su-Gi therapy. And that individual names are to be classified and separated as the type or method of Su-Gi therapy. 3.

To prospectively determine the diagnostic performance a combination of standard bolus-chase magnetic resonance (MR) angiography and MR angiography with time-resolved imaging of contrast kinetics (TRICKS) for depicting severity of the head and neck vascular diseases. Over a period of two months, A total of 100 patients(average ages : $50{\pm}8$, male : 60, female : 40) with head and neck vascular diseases were performed on the GE excite 3.0 T units with 8-channel head coil and 4-channel NV coil. Imaging parameters for a typical study were as follow: SBC(TR/ TE/ FA/ SliceThicken./ Slab/ Freq./ FOV/ BW/Scan Time) = 5.4/ min/ 30/ 2/ zip2/ 70/ $224{\times}448$/ 30/ 62.50/ 28, TRICKS(TR/ TE/ FA/ Slice Thicken/Slab/ Freq./ FOV/ BW/ Temp Res./ Scan Time = 3.6/ min/ 25/ 4/ 30/ $160{\pm}384$, zip512/ 30/ 100/ 1 to 1.5/ 23). The analysis of all MR images, which have respect-ively classified two techniques into some diseases. The results of the former were divided into two groups(SBC, TRICKS)with 4 grading of two reader, respectively. Wilcoxon signed rank test was used to determine if a significant difference between imaging techniques existed(p < 0.05). In 33 of 100 patients, arterio-venous malformation was 11% at TRICKS, subclavian vein stenosis : 8%, fistular sinus : 4%, jugular vein stenosis:6%, Middle Cerebral Artery bypass surgery : 4%, p < 0.05). The rest of 67 patients were considered as the results of SBC(14% in the basilar artery stenosis, carotid stenosis : 16%, vertebral stenosis : 17%, central neuro-cytoma : 5%, meningioma : 5%, Not appliable : 10%, p < 0.05). Sensitivity and specificity of TRICKS MR angiography in SVS, FS, JVS, MCABS were improved compared with those at standard MR angiography. In SBS MR angiography which were improved in BAS, CS, VS, CN, Meningioma. In conclusion, TRICKS MR angiography of the SVS, FS, JVS, MCABS is superior to standard MR angiography regarding the number of diagnostic grading. The SBS MR angiography were improved in BAS, CS, VS, CN, Meningioma. and assessment of the degree of luminal narrowing on both TRICKS and SBS.

Gastric cancer is one of the most common cancers in Korea and the world. Since 2004, this is the 4th gastric cancer guideline published in Korea which is the revised version of previous evidence-based approach in 2018. Current guideline is a collaborative work of the interdisciplinary working group including experts in the field of gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology and guideline development methodology. Total of 33 key questions were updated or proposed after a collaborative review by the working group and 40 statements were developed according to the systematic review using the MEDLINE, Embase, Cochrane Library and KoreaMed database. The level of evidence and the grading of recommendations were categorized according to the Grading of Recommendations, Assessment, Development and Evaluation proposition. Evidence level, benefit, harm, and clinical applicability was considered as the significant factors for recommendation. The working group reviewed recommendations and discussed for consensus. In the earlier part, general consideration discusses screening, diagnosis and staging of endoscopy, pathology, radiology, and nuclear medicine. Flowchart is depicted with statements which is supported by meta-analysis and references. Since clinical trial and systematic review was not suitable for postoperative oncologic and nutritional follow-up, working group agreed to conduct a nationwide survey investigating the clinical practice of all tertiary or general hospitals in Korea. The purpose of this survey was to provide baseline information on follow up. Herein we present a multidisciplinary-evidence based gastric cancer guideline.

Lymphomatoid granulomatosis, polymorphic reticulosis, midline malignant reticulosis, or lethal midline granuloma have similar histologic features of an angiocentric and angiodestructive lymphoreticular proliferation representing the same nosologic entity. The term 'angiocentric immunoproliferative lesion' (AIL) was proposed by Jaffe, Costa, and Martin. The malignant potential of AILs is originally uncertain, but the facts that AILs have a relatively short survival, and most of them usually progress to an overt malignant lymphoma and survival is inversely proportional to the large, atypical lymphoreticular cells suggest that AILs are malignane. We experienced 17 AILs in nose during 16-year period and retrogradely analized them to recognize the problems in the diagnosis and to establish the further therapeutic strategies. The results were as follows; Twelve of total 17 patients who had diagnosed as histologic grade 1 and 2 had received radiation therapy as an initial treatment and the complete response rate was 91.7%(11/12), but 6 out of 11 had local recurrence and 5 had progress to overt maligant lymphoma within 2years. Three patients with the histologic grade 3 and 2 with unclear histologic grade had received CHOP chemotherapy and there was 1 case with complete response. Two patients with unclear histologic grade had been proved to be malignant histiocytosis by bone marrow biopsy during the clinical course. The overall duration of survival was 2 - 119 months and the 5-year survival rate was 71.9%. And the achievement of initial complete response was the most important prognostic factor of overall survival(P=0.006). Our results suggest that the treatment strategy according to the histologic grading scheme is efficient and more aggressive combination chemotherapy may be necessary to achieve complete response in patients with histologic grade III and II, because most of them progress to overt malignant lymphoma during its process.
